Posted 11 October 2019, 5:17 am ESTThe window is themed with C1ThemeController. This does not happen very often, so it is hard to repeat. But it did happen a few times to me. This happens on startup, so there is no particular action that triggers it. In the video I am attaching you can see it happen as I resize the window.
If I switch the theme away from Black (and even if I switch it back to Black afterwards) the glitch goes away.
Do you have any suggestion about how I can fix this?
